Clothianidin is an insecticide developed by Takeda Chemical Industries and Bayer AG. Similar to thiamethoxam and imidacloprid, it is a neonicotinoid. Neonicotinoids are a class of insecticides that are chemically similar to nicotine, which has been used as a pesticide since the late 1700s. Clothianidin and other neonicotinoids act on the central nervous system of insects as an agonist of acetylcholine, the neurotransmitter that stimulates nAChR, targeting the same receptor site (AChR) and activating post-synaptic acetylcholine receptors but not inhibiting AChE. It has been thought that the advantage of clothianidin and other neonicotinoids over nicotine is that they are less likely to break down in the environment. Recent (2012) studies show that pesticide dust released at planting time may persist in nearby fields for several years and be taken up into non-target plants, which are then foraged by bees and other insects.
Clothianidin is an alternative to organophosphate, carbamate, and pyrethroid pesticides. It poses lower risks to mammals, including humans, when compared to organophosphates and carbamates. It has helped prevent insect pests build up resistance to organophosphate and pyrethroid pesticides.[1][2][3]
According to the Environmental Protection Agency (EPA), clothianidin's major risk concern is to nontarget insects (honey bees). Although EPAs Environmental Fate and Effects Division does not conduct risk assessments on non-target insects, information from standard tests and field studies, as well as incident reports involving other neonicotinoid insecticides (e.g., imidacloprid) suggest the potential for long term toxic risk to honey bees and other beneficial insects.[4] In January 2013, the European Food Safety Authority stated that neonicotinoids including clothianidin pose an unacceptably high risk to bees, and that the industry-sponsored science upon which regulatory agencies' claims of safety have relied is flawed and possibly deliberately deceptive, concluding, "A high acute risk to honey bees was identified from exposure via dust drift for the seed treatment uses in maize, oilseed rape and cereals. A high acute risk was also identified from exposure via residues in nectar and/or pollen.
